Thanks for the reply! I am still a little hung up on accounting for the boundary condition of F'(Inf) = 1, how do I account for this? I've only dealt with initial conditions before, which are much more obvious. Thanks!

Homework Statement Edit* should say F'(0) = F(0) = 0 Homework Equations I know that I typically need 3 equations for a 3rd order ODE, does this apply if the is no F'? In the picture above are the equations I came up with, am I on the right trail? Lastly I am familiar with RK4, however I have...

Homework Statement Homework Equations I could really use a push on how to approach this problem. My primary problem is it asks for the heat flux into the page, which makes no sense to me as that is the z direction and this is in the x/y plane. If anyone could explain this problem and maybe...

This is what I used.

I'm very confused. I used the flexure formula for arbitrarily applied moments, it utilizes superposition. so was my approach right or wrong? I'm really not following what your getting at... I'm ok with doing a little extra calculation but I have no idea what calculations to do... the only thing...

or stresses for that matter? also I'm not following what situation the flexure formula is valid...

can moments be added using Pythagoras?

it seems to me that I would in fact have to use Pythagoras to add them, but would that work? sorry I have looked through my strengths book and the text for this class and cannot find how to add them.

Because they seem to be combining for the greatest stress at essentially 45° (Unit circle), can I use trig to add them together?

Looking at this picture it seems as though we have some areas adding, and others cancelling. It looks to me as though where the stress is max is at the two corners where we have the same sign, one tensile, one compressive. conceptually it makes sense, however I'm still unsure as to how I am...

35 feet. Thank you for pointing this out, I will fix it in the original question. Also I thought it was odd to add the two stresses without having to do Pythagorean, however when looking through my strength of materials book the flexure formula shows them adding stresses due to bending moments...

Homework Statement It's been a while since I've done this, it's essentially a strength of materials problem in my mechanical analysis class so I haven't worked problems like these in quite a a while. I'm fairly confident I've done it right however I was hoping someone might be able to confirm...

Homework Statement I have two conceptual questions that I have written in read in my solution. The solution, and all the work, is correct. However there are two things that I am unsure as to why I am doing it. Thanks! Homework Equations Included in solution, although none should be needed as...

Figured it out, bounds were incorrect. X axis was in terms of percentage increase, not actual increase.

Homework Statement The problem is asking to find the change in temperature of forged cylinder. I know how to calculate this, , however I am struggling to find the work done on the cylinder, which is required to solve this problem. The cylinder is annealed copper, which is compressed from a...
